Game designers from across North America are gathering here in Toronto today for X'09, Microsoft's annual Xbox 360 preview event. I'll be spending today looking at the hottest games coming this holiday season from a number of top publishers, including Activision, UbiSoft, and Electronic Arts, plus I'll be given a look at the next set of changes for Microsoft's Xbox Live online service. While I will post details here on my blog after the showcase wraps up, I will also be sending out pictures and quick tidbits over my Twitter account here.
